HTML is not fragmentable in a meaningful manner. Tp fragment HTML, you must first parse the document, and if you do that, byte ranges make almost no sense as a unit of fragmentation. I will be sending an RFC out one day about this. >To repeat: just because a file's fragments aren't valid file types on >their own doesn't mean they're not useful.

What happens if this range of bytes actually references a document that has changed recently? The user will get a page with a (probably) garbage sample. Not robust....
